Cubic silicon carbide, Beta SiC, is a synthetic high-performance material (only a small amount of high-purity cubic silicon carbide exists in nature). It is called "cube" because its structure belongs to the cubic system (diamond crystal). This structure also determines its own superior physical and chemical properties. B-SiC has a Mohs hardness range of 9.5 to 9.75, which is close to the most Moh...
